Despite a rising interest in optics, commercial AM systems cannot break the 20 micron resolution barrier. Electrohydrodynamic jet printing has emerged as a promising high-resolution AM process capable of reaching resolutions ranging from 10’s nm to 100’s microns with a wide range of materials.
Two dimensional (2D) nanomaterials exhibit exciting optoelectronicand mechanical properties, making them idelaly suited for emerging photonic applications. In this talk, we will disuss using large scalable synthesis techniques and laser processing strategies to enable high performing flexible 2D photonic materials and devices.
Self-collimating spatially-variant lattices (SVLs) are integrated photonic devices that can be designed to steer optical beams in 3D within micron-scale volumes. SVLs can be fabricated by multi-photon lithography, and new routes to these and related devices are being explored based on modified Bessel beams.
Metamaterial fabrication by two-photon polymerisation is suggested. Altering fabrication parameters (laser power and scan speed) controls the resulting line widths. Understanding possible line widths is key to understanding how the geometry can be changed across a metamaterial device leading to gradient index (GRIN) optics.
Here, we demonstrate a novel method of transferring 2D materials resembling the functionality known from printing; utilizing a combination of a sharp micro-stamper and viscoelastic polymer, we show precise placement of individual 2D materials on Si photonic platform without any cross-contamination.
